Hello, I am a newbie so be gentle. I have been thinking of getting into the RC world and have been watching Craigslist to purchase one. My question is, For my first 'real' RC vehicle is it ok to buy used or am I always better off to purchase new? I have found an Emaxx that has RPM A-arms and shock towers. He says he has never ran a lipo battery on it and is asking $300 for it. should I buy, negotiate or run?
